Re: Page pool hard limit and page instance usage
Hi again,
I'm hitting my head to wall here with ServletContextSymbolProvider. It is
configured like this:
public static void
contributeSymbolSource(OrderedConfigurationSymbolProvider configuration,
@InjectService(ServletContextSymbolProvider) SymbolProvider
servletContextSymbolProvider)
{
configuration.add(ServletContextSymbolProvider ,
servletContextSymbolProvider, after:SystemProperties,
before:ApplicationDefaults);
}
public static ServletContextSymbolProvider
buildServletContextSymbolProvider(ApplicationGlobals globals){
return new
ServletContextSymbolProvider(globals.getServletContext());
}
And it always ends to this error:
java.lang.RuntimeException: Unable to instantiate class

I can't determine where the recursion is. Is the ApplicationGlobals
initiating the construction of Alias service? If this is true then
ApplicationGlobsals cannot be used while I'm constructing my alias
overrides?
Is there anyone out there who has this working?

Re: IoC Question with Alias
hi michael,
happened to me several times too :)
first you could try to define your services as proxy:
from:
binder.bind(HttpdRequestSecurityManager.class).withId(HttpdRequestSecurityManager);
to:
binder.bind(RequestSecurityManager.class,
HttpdRequestSecurityManager.class).withId(HttpdRequestSecurityManager);
if this is not enough try to break the dependency cycle by
injecting the ObjectLocator and creating the proxy manually
eg:
configuration.add( AliasContribution.create(
RequestSecurityManager.class,
locator.proxy(
RequestSecurityManager.class,
HttpdRequestSecurityManager.class)) );

IoC Question with Alias
Hi,
I have a problem with the contributions to the alias service. The
AppModule is ...
public static void bind( ServiceBinder binder ) {
binder.bind( SiteDispatcher.class ).withId( SiteDispatcher );
binder.bind( SiteServiceImpl.class ).withId( SiteService );
binder.bind( HttpdRequestSecurityManager.class ).withId(
HttpdRequestSecurityManager );
binder.bind( SiteBaseURLSource.class ).withId( SiteBaseURLSource );
}
@SuppressWarnings( unchecked )
public void contributeAlias(
ConfigurationAliasContribution configuration,
@InjectService( HttpdRequestSecurityManager )
RequestSecurityManager manager,
@InjectService( SiteBaseURLSource )
BaseURLSource baseUrlSource ) {
configuration.add( AliasContribution.create(
BaseURLSource.class,
baseUrlSource ) );
configuration.add( AliasContribution.create(
RequestSecurityManager.class,
manager ) );
}
The constructors of the services are ...
public SiteServiceImpl(
RequestGlobals globals,
ApplicationGlobals application,
Session session,
Logger logger,
CollectionString contributions,
SymbolSource symbols ) {
...
}
public HttpdRequestSecurityManager(
Request request,
Response response,
MetaDataLocator locator,
RequestPageCache requestPageCache,
@InjectService(SiteBaseURLSource)
BaseURLSource baseURLSource,
SiteService site ) {

}
public SiteBaseURLSource( SiteService site ) {

}
I get the [ERROR] Alias Construction of service Alias failed: Error

Re: NPE when trying to contribute ServletContextSymbolProvider to SymbolSource (WAS: Re: Page pool hard limit and page instance usage)
A Filter is passed a FilterConfig object where you can call
getServletContext() and get the ServletContext. So the availability
shouldn't be a problem. I rather believe that it doesn't get set in
ApplicationGlobals until a certain point which is after building the
SymbolSource...

Environmentals are not regular services, they're pushed onto a stack at the right time during rendering, often with specific configuration, so it doesn't make sense to persist them. -Filip On 2008-09-22 16:34, Peter Stavrinides wrote: I am upgrading from 5.0.14 to 5.0.15, and have come across this error several times: Caused by: org.apache.tapestry5.internal.services.TransformationException: Field _tabList of class pages.hf.Fund is already claimed by @org.apache.tapestry5.annotations.Persist and can not be claimed by @org.apache.tapestry5.annotations.Environmental Probably some foul coding on my part, but I am having trouble understanding exactly what I have botched up, obviously the field is in conflict, Persist and Environmental don't play nice together anymore, why though? and what is the correct approach?

DateField + FCK possible bug?
HI, I do not know hwther it is a bug or not. Happens on T5.0.14 and .15. In safari 3.1.2 : When I have FCK and DateField on the same page, little calendar is not clickable. In FF 3: Calendar is clickable, but: In case I have predefined value in page code, ex: private Date dateOfFoo = new Date(), the calendar after clicking is empty and the header says NaN Undefined. If I do not predefine, the calendar is ok. -- Pozdrawiam, Dariusz Dwornikowski ProAdmin ul.

Re: Integration with GWT
I am also interested in a basic but complete tutorial on using GWT in T5. Anyone want to share some sample setup/source code or give some pointers?

There is great widget library for GWT to serve Google Maps with all their AJAX stuff, so I decided to use it also. Please, give me some information whether it's possible to integrate full lifecycle of GWT component with T5 as main framework? What I actually need is to be able to share some objects between Tapestry and GWT, but without page reload. So my GWT component should make its RPCs as usual, but these calls should be made after pressing button in Tapestry component and information should be got from that component too (@ApplicationState may be, but how to integrate it with GWT?)

Hi All, Sorry for this off-topic post. I have just moved to Montreal, Canada and Im wondering if anyone knows any companies that use Tapestry and have a development office in Montreal. I am quite keen to keep working with Tapestry. Any help would be greatly appreciated. -- View this message in context: http://www.nabble.com/JOB-tp19613380p19613380.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5Components Inside AjaxResult - delay in loading javascript files
I got it!
It was not a delay. Tapestry.DEBUG_ENABLED was set true.
I used the renderSupport to turn it off.
public void afterRender()
{
renderSupport.addScript(Tapestry.DEBUG_ENABLED = false;);
}
Now it is working fine!
Thank you,

Hi All,
When I use any of the T5Components inside the Ajax Result there is a

The T5Component, InPlaceCheckbox, is inside someBlock which is the result

Find the java and tml code below.
Is there any one who can help me to avoid the delay?

[T5] GridDataSource: why call getAvailableRows before prepare?
I'm starting to use Grid to display the paged, sortable results of a Hibernate query, so I'm implementing GridDataSource. I was dismayed to see that getAvailableRows gets called before prepare. This means that I have to run my query twice: once to count the total rows (when getAvailableRows gets called), and again to do the sorting and get the correct page (when prepare gets called). If, instead, prepare got called first, then I could do the sorting and page extraction and get the total number of results all in one query (just add count(*) to the columns being returned). You might ask, how can the system know the page size to ask for when calling prepare if it hasn't called getAvailableRows first? No problem: just ask for the first full page and have prepare return the number of rows it actually found. (Or add a getter for that information.) For fast queries, running them twice isn't that great a sin, but for slow queries, such as in a user-specified search page, running them twice when you don't really have to seems extravagant to me. -- View this message in context: http://www.nabble.com/-T5--GridDataSource%3A-why-call-getAvailableRows-before-prepare--tp19616074p19616074.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tapestry components are statically bound
We are building a large Tapestry application with hundreds of tapestry components. One size and performance concern we've encountered along the way is the fact that tapestry components are statically bound (i.e. all components on a page are always instantiated and bound, even though @If will omit the component from rendering). (NOTE: if relevant, we are using Tapestry 4.02, so perhaps this behavior is different on the 4.1 line?) For example, div jwcid=@widgets/ListingHeader item=ognl:curItem/ div jwcid=@widgets/InquireHeader item=ognl:curItem/ In the above example, all three components (ListingDetail, InquireDetail, and PurchaseDetail) get instantiated and parameters bound, despite only one being necessary. Considering each component may have a hierarchy of components itself, this could quickly pull in lots of extra stuff unnecessarily. First question, is this really a problem or completely necessary due to page pooling (i.e. perhaps tapestry must instantiate all components or else pages can't be pooled and used again with different conditions) ?? Second, is there a way (either in core Tapestry or through extensions) to instantiate and bind only the components that @If logic includes? If not, any thoughts on how to build such a dynamically bound component in tapestry? Third, we could reduce this problem and simplify the above example if we could write this one-liner instead of the string of @If statements: Clearly, Tapestry doesn't support ognl expressions in jwcid expressions, but why not? Again with the pooling, would making some components late bound like this render their pages un-poolable? Or could this pooling problem be worked around (i.e. lazy-load the component upon first access) ??

Re: NPE when trying to contribute ServletContextSymbolProvider to SymbolSource (WAS: Re: Page pool hard limit and page instance usage)
Should I add Jira about this?
After all, it is pretty pointless to have this symbol provider if it can't
work. (Perhaps there is some way to overcome this problem?)

Subject: NPE when trying to contribute ServletContextSymbolProvider to

The problem seems to be, that the ServletContext provided by
ApplicationGlobals is null when Tapestry tries to contribute the
ServletContextSymbolProvider to the SymbolSource service. I don't know
why
this is the case. Maybe someone else can shed some light on this.
